Description

Technical Field

[0001] This utility model relates to the technical field of coil winding equipment, specifically a high-frequency pulse transformer coil winding fixture. Background Technology

[0002] The transformer coil of a high-voltage pulse transformer is a key component, and its design parameters, shape, and manufacturing process have a significant impact on the performance, quality, and safety of the high-voltage pulse transformer.

[0003] A search revealed a patent, CN114743791A, which discloses a winding device for a high-frequency transformer coil. The device includes a mounting base plate. Positioning plate two and positioning plate one are fixedly connected to the left and right sides of the upper surface of the mounting base plate, respectively. Positioning plate one has a through hole on its outer wall, through which a spline sleeve is rotatably connected. A spline shaft is inserted into the inner wall of the spline sleeve. A connecting pipe draws outside air into a blower, which then inputs air to a jet nozzle. This jet sprays air onto the surface of the winding wire wound on the outer wall of the iron core rod, preventing dust or impurities from getting trapped inside the winding wire during the winding process and affecting its cleanliness. After the cleaning roller carries the winding wire through one layer on the outer wall of the iron core rod, the cleaning roller reverses its direction of movement, thereby driving the winding wire to wind the next layer on the outer wall of the iron core rod, achieving the function of multi-layer winding and improving the continuity and tightness of the winding.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In reality, there are many types of high-voltage pulse transformers, and the length and size of their core rods vary. The aforementioned comparative documents can only be used to fix and wind core rods of the same size, which reduces the applicability of the coil winding fixture. Therefore, there is an urgent need in the field to improve the coil winding fixture for high-frequency pulse transformers in order to overcome the shortcomings of the existing technology.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] Please see Figures 1-8A high-frequency pulse transformer coil winding fixture includes a vertical support column 1, a lower support frame 2 fixedly installed on the lower side of the vertical support column 1, a top plate 3 at the upper end of the vertical support column 1, a telescopic device 4 with a telescopic effect fixedly installed at the lower part of the top plate 3, an upper support frame 5 fixedly installed at the lower end of the telescopic device 4, and support seats 6 rotatably connected to the opposing sides of the upper support frame 5 and the lower support frame 2. Several equidistant and circumferentially arranged sliding rack plates 8 are slidably connected inside the support seats 6. A clamping block 16 adapted to the side of the end of the iron core rod 7 is provided on one side of the sliding rack plates 8. A synchronous drive unit 9 is provided on the support seats 6 for synchronously driving the several sliding rack plates 8 to move in opposite directions or back to back. A winding guide unit 10 is provided on the vertical support column 1 for guiding the winding. The upper part of the support column 1 is provided with an upper and lower drive unit 11 for driving the winding guide unit 10 to move up and down. The lower support frame 2 and the upper support frame 5 are both fixedly installed with a first drive motor 12 for rotating the support seat 6. The vertical support column 1 is provided with a main controller 13 on one side. The synchronous drive unit 9 includes a second drive motor 14 fixedly installed on one side of the support seat 6. The support seat 6 is rotatably connected with a rotating gear ring 15 that is misaligned with the sliding rack plate 8. Several gears 17 are rotatably connected to the support seat 6. The gears 17 mesh with the side of the rotating gear ring 15 and the side of the sliding rack plate 8. One side of the clamping block 16 does not exceed the inner wall of the iron core rod 7. One side of the clamping block 16 is fixedly connected with a mounting plate 30. The clamping block 16 is fixedly installed on the sliding rack plate 8 through the cooperation of the mounting plate 30 and bolts.

[0031] In this specific embodiment, the copper wire needs to be wound around the side of the core rod 7 during the production of a high-frequency pulse transformer. The core rod 7 to be wound is placed vertically on the upper part of the lower support 6, and the core rod 7 is located between several clamping blocks 16. The telescopic device 4 is activated by the main controller 13. The telescopic end of the telescopic device 4 drives the upper support frame 5 to move down. The support 6 at the lower part of the upper support frame 5 moves down to the lower part and touches the upper part of the core rod 7. At the same time, the synchronous drive unit 9 on the two support 6 is activated, and the second drive motor 14 is turned on. The output of the drive motor 14 drives one of the gears 17 to rotate, which in turn drives the rotating gear ring 15 to rotate. The rotating gear ring 15, in turn, drives the other gears 17 to rotate. The simultaneous rotation of several gears 17 drives the sliding rack plate 8 to move, which in turn drives the clamping blocks 16 to move. The clamping blocks 16 move towards each other and clamp the upper and lower sides of the iron core rod 7. The copper wire to be wound is then placed on the side of the iron core rod 7 via the winding guide unit 10. The first drive motor 12 is then activated. The bearing seat 6 rotates to wind the coil, and the upper and lower drive unit 11 is activated simultaneously. The upper and lower drive unit 11 drives the winding guide unit 10 to move up and down slowly. The speed of the winding guide unit 10 is matched with the speed of the rotation of the iron core rod 7 until the winding of the coil is completed. Several clamping blocks 16 that can move synchronously in opposite directions can clamp and fix iron core rods 7 with different outer diameters. The upper bearing frame 5 moves up and down through the telescopic device 4, which can clamp and fix iron core rods 7 with different heights, improving efficiency. The efficiency and applicability of this coil winding fixture are excellent. One side of the clamping block 16 does not exceed the inner sidewalls of both ends of the iron core rod 7, so it will not hinder the winding of the coil. At the same time, the clamping block 16 can be replaced according to the iron core rod 7 to be wound. The appropriate clamping block 16 is selected and fixed on the sliding rack plate 8 by bolts and mounting plate 30. The installation position of the clamping block 16 on the sliding rack plate 8 is adjustable, which can position and clamp iron core rods 7 with rectangular or other shapes at both ends, further improving the efficiency of coil winding on the iron core rod 7.

[0033] In this specific embodiment, the coil to be wound is pressed between two guide rollers 20. By starting the third drive motor 21, the output end of the third drive motor 21 drives the drive screw 25 to rotate. When the drive screw 25 rotates, it drives the moving seat 22 to move in the moving groove 24. The moving seat 22 drives the moving frame 18 to move. The moving frame 18 moves in the through hole 23, thereby achieving the limiting and guiding effect of the wound copper wire. Example 3

[0035] In this embodiment, two guide rollers 20 clamp the copper wire, and the limiting plate 28 can move within the hollow tube 26. The connecting column 27 can move. Through the tension of the spring 29, the two guide rollers 20 always ensure that the copper wire is pressed tightly.
